Wait 'Til Helen Comes is a good book. Molly is the big sister,michael is the little brother Dave is the guy that married their mom and Dave has a daughter her name is Heather Elizabeth Hill. Heather's mom died in a fire. The story starts off by the family buying a church to live in near the woods and a creek in the woods there is a cemetery,there is a tombstone with the initials H.E.H. In the begining I thought that the tombstone was going to be the tombstone of Heather when she die,but then I started to read more of the book and it said that the initials were Helen Elizabeth Harper. I really like this book if you like scary stories you should read this one I think you will like it. I'm sure you'll like the ending.
